DIGITAL SIGNAL TRANSMISSION
The design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer engineering.
With this board the students can study the operating principle of the transmission of digital signals using the most common modulations such as ASK, FSK and PSK with the aid of encoders/decoders NRZ, RZ, Manchester, Biphase and Duo-binary.
